Sharing an RStudio.Cloud Project, and Copying the Project to Convert it from Temporary to Saved

When sharing an project via distributing the URL, it is said that initially, this project will be temporary and changes will not be saved automatically.
How do you save the project so that new changes are not lost?

When a student goes to your shared project they'll see a blinking red text that says "TEMPORARY COPY" and next to it is a button to "Save a Permanent Copy".

Once the student is working in their permanent copy, changes will be saved to this new project.
